CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent ApplicationNo. 61/174,954, filed on May 1, 2009, which is hereby incorporatedherein by reference.

FIELD OF THE INVENTION

The invention relates generally to systems and methods of providing dataservices in a mobile environment, and in particular without requiringin-vehicle or personal navigation systems to interoperate with.

BACKGROUND OF THE INVENTION

Satellite digital radio broadcasters, such as, for example, Sirius XMRadio Inc. (“Sirius XM”), currently offer well over a hundred channelsof content over a large geographic footprint. A portion of that contentcan include data services that interoperate with existing GPS-basednavigation services commonly available for use in automobiles, forexample. Such data services can include, for example, traffic data,weather data, etc. For example, Sirius XM has operated real-time trafficdata services for premium navigation systems since 2004. These servicesprovide a subscriber with real-time traffic information, enabling avehicle's navigation system or Personal Navigation Device (“PND”) todisplay constantly refreshed and current traffic conditions. However,for the large portion of the existing and future markets that do not orwill not have access to GPS-based navigation systems, these dataservices are useless.

In a typical satellite radio service configuration of approximately 100channels or more, nearly 50 channels provide music with the remainingstations offering news, sports, talk and data. For example, thebroadcast services provided by Sirius XM Radio Inc. each include asatellite X-band uplink to two or more satellites which providefrequency translation to the S-band for re-transmission to radioreceivers on earth within a coverage area. Radio frequency carriers fromone of the satellites are also received by terrestrial repeaters. Thecontent received at the repeaters is retransmitted at a different S-bandcarrier to the same radios that are within their respective coverageareas. These terrestrial repeaters facilitate reliable reception ingeographic areas where geosynchronous satellite reception is obscured bytall buildings, hills or other natural obstructions, tunnels, or otherobstructions. The signals transmitted by the satellites and therepeaters are received by satellite digital audio radio system (“SDARS”)receivers which can be located in automobiles, in handheld units, or instationary units for home or office use. The SDARS receivers aredesigned to receive one or both of the satellite signals and the signalsfrom the terrestrial repeaters and dynamically combine or select one ofthe signals to output to a user.

Each SDARS receiver generally contains a unique Hardware Identificationnumber (HWID), which is assigned during the manufacturing process. TheHWID can be used by SDARS Service Providers to enable the receiver toreceive, or disable the receiver from receiving, particular subscribedservices such as music and talk programming. In addition, thesesubscribed services can include data services, such as, for example,weather and traffic data feeds or other custom data feeds. Such customdata feeds are typically uniquely enabled by the SDARS Service Providerfor select subscriber groups.

Additionally, current navigation services store databases of maps andother data and rely on complicated navigational systems, routingengines, embedded map databases and other resources to provide theirinformation to users, all of which adds complexity and cost.

What is thus needed in the art are systems and methods of providing dataservices to users in an automotive environment without requiring, orbeing dependent upon navigation systems

SUMMARY OF THE INVENTION

In exemplary embodiments of the present invention, a suite of dataservices can be provided for non-navigation based head units that canprovide similar levels of functionality to navigation-based systems. Anon-navigation data system for providing data services in a mobileenvironment can include a data decoder for decoding a digital datastream from a digital audio radio transmission source, a locationdetermining means for determining a current location of a mobilereceiver receiving the digital data stream, a display for displayingdata corresponding to the current location, and a plurality of staticmaps wherein the data corresponding to the current location is overlaidat least over a portion of the static maps. In exemplary embodiments ofthe present invention, a method of providing a data service in a mobileenvironment without the need for a navigation system can includedecoding a digital data stream from a digital audio radio transmissionsource, determining a current location of a mobile receiver receivingthe digital data stream, displaying data corresponding to the currentlocation, and overlaying the data corresponding to the current locationover at least a portion of a plurality of static maps.

DETAILED DESCRIPTION OF THE INVENTION

Satellite radio operators are providing digital radio broadcast servicescovering the entire continental United States with the hope of furthercovering other areas of the Americas. These services offer approximately100 channels or more, of which nearly 50 channels in a typicalconfiguration provides music with the remaining stations offering news,sports, talk and data channels. Briefly, the service provided by SiriusXM Radio includes a satellite X-band uplink to two satellites whichprovide frequency translation to the S-band for re-transmission to radioreceivers on earth within a coverage area. Radio frequency carriers fromone of the satellites are also received by terrestrial repeaters. Thecontent received at the repeaters is retransmitted at a different S-bandcarrier to the same radios that are within their respective coverageareas. These terrestrial repeaters facilitate reliable reception ingeographic areas where Geosynchronous Satellite reception is obscured bytall buildings, hills or other natural obstructions, tunnels, or otherobstructions. The signals transmitted by the satellites and therepeaters are received by satellite digital audio radio system (SDARS)receivers which can be located in automobiles, in handheld or instationary units for home or office use. The SDARS receivers aredesigned to receive one or both of the satellite signals and the signalsfrom the terrestrial repeaters and combine or select one of the signalsas the receiver output.

Each SDARS receiver contains a unique Hardware Identification number(HWID), which is assigned during the manufacturing process and is usedby SDARS Service Providers to enable or disable the radio to receivesubscribed services, such as music and talk programming. In addition,these subscribed services could include data services, such as weatherand traffic data feeds or other custom data feeds. The custom data feedsare typically uniquely enabled by the SDARS Service Provider for selectsubscriber groups. Although existing telematics systems using cellularand Global Positioning System (GPS) technology such as the On-Starsystem currently track vehicles and provide services such as dispatchingemergency road side assistance upon detection of certain detected eventsat the vehicle, no existing system graphically provides enhanced dataservices without providing a navigation system that typically requiresadditional memory and resources to operate.

In exemplary embodiments of the present invention data services areoffered that expand the range of target head units from navigation basedsystems to non-navigation based systems. In order to deliver afunctional suite of data services, the following hardware and systemconfiguration can be assumed: (i) GPS present or a cellular locationdetermining mechanism using time distance of arrival for example orother technique; (ii) nNo on board maps or routing database; (iii) anAlert-C decoder in the head unit to decode the Sirius XM non-navigationtraffic messages.

In exemplary embodiments of the present invention the data services caninclude, for example, the following:

1. Weather—presented as graphical and tabular data. The tabular weatherservice can be based on an existing data feed, and can, for example,mirror current weather markets;2. Fuel prices—provide pricing data for x stations y miles from vehicle;3. Movie times—provide schedule data for x theaters y miles fromvehicle; and4. Sports scores—can be identical, for example, to the Sirius TravelLink® service, described at, for example, the following URL:http://fordvehicles.com/assets/modules/sirius/brochures/Travel_Link_Brochure_ford.pdf,which is hereby incorporated herein by reference.

In exemplary embodiments of the present invention GPS can be used topresent relevant weather data to users, based on the weather marketassociated with the user's then current location. Additionally, acustomer can select an alternate weather market from drop down menu,speech recognition, or other user friendly input method. In exemplaryembodiments of the present invention no modification required to theweather data feeds currently used by SDARS providers in connection within-vehicle navigation systems. Thus, in exemplary embodiments of thepresent invention, a non-nay tabular weather service can be essentiallyidentical to a navigation system based service

FIGS. 1 and 1A depict exemplary screen shots of tabular weather on anon-nay system according to an exemplary embodiment of the presentinvention. FIG. 1, for example, displays a 5 day forecast for theDetroit area, and FIG. 1A has a combined current weather conditions and5 day forecast display.

FIG. 2 depicts an exemplary screen shot of a graphical weather displayaccording to an exemplary embodiment of the present invention. Such agraphical weather service can be based on existing data feeds used bySDARS providers in connection with navigation-based data services. Withreference thereto, a country can be divided into a 16 tile map, matchingthe WSI tiles, and weather data can be, for example, overlaid onto themap. In exemplary embodiments of the present invention, there can be aoption to display a nationwide view of graphical weather. As shown inFIG. 2A, alternatively, a country or area can be divided into adifferent number of tiles, such as, for example, twelve. In exemplaryembodiments of the present invention, up to four tiles of such weatherdata can be used to display one tile of pertinent weather information.

FIG. 3 depicts an exemplary screen shot of fuel prices data according toan exemplary embodiment of the present invention. With referencethereto, distance and direction to each station is displayed. Unlike amore cumbersome navigation system, here, for example, no detailedrouting to a given gas station need be provided, just rough directionalinformation. FIG. 3A depicts an alternate exemplary embodiment, wherethe oil company logo is displayed at the far left, and the relativelocation of each listed gas station can be displayed overlaid on a map.

In exemplary embodiments of the present invention there can be providedan option to sort stations by price or distance to vehicle's thencurrent position. In exemplary embodiments of the present invention sucha fuel price data service can be implemented, for example, with minor orno modification required to existing fuel price data feeds used inconnection with navigation systems.

FIG. 4 depicts an exemplary screen shot of local movie listingsaccording to an exemplary embodiment of the present invention, and FIG.4A depicts a screen shot of an alternate exemplary embodiment of thisdata service. In such exemplary embodiments, both distance and directionto theater can be displayed in the same manner shown for fuelingstations in FIGS. 3 and 3A.

In exemplary embodiments of the present invention, a non-nay based movieinformation service can be based on existing data feeds used inconnection with navigation-based systems. In exemplary embodiments ofthe present invention there can be provided an option to sort theatersby movie, theater, or proximity to then current location of vehicle. Inexemplary embodiments of the present invention such a fuel price dataservice can be based on, and can be implemented, for example, with minoror no modification required to existing movie information data feedsused in connection with navigation-based systems. Thus, such exemplarynon-nay based movie information services can be, for example,essentially identical to similar navigation system based movieinformation services.

FIG. 5 depicts an exemplary screen shot of a sports scores data serviceaccording to exemplary embodiments of the present invention. FIG. 5Adepicts an alternate exemplary screen shot of this service according toalternate exemplary embodiments of the present invention. In exemplaryembodiments of the present invention, a non-nay based sports scoreinformation service can be based on existing data feeds used inconnection with navigation-based systems. Additionally, in exemplaryembodiments of the present invention, a non-nay based sports scoreservice can be based on, and provided with no or minor modification toexisting sports information data feeds used by SDARS providers inconnection with navigation-based systems. Thus, no modifications arerequired to existing in-vehicle sports data human machine interfaces(“HMI”), and such an exemplary non-nay based sports score service canbe, for example, essentially identical to similar navigation-basedsports score services, such as, as noted above, the Sirius Travel Link®service.
